Product overview

The CMOD-02 multifunction extension module (external 24 V AC/DC and isolated
PTC interface) has a motor thermistor connection for supervising the motor
temperature and one relay output, which indicates the thermistor status. In case
the thermistor overheats, the drive trips on motor overtemperature. If Safe torque
off tripping is required, the user must wire the overtemperature indication relay
to the certified Safe torque off input of the drive.
In addition, the extension module has an external power supply interface, which
can be used to power up the drive control unit in case the drive power supply is
not on. If you do not need the back-up power supply, you do not have to connect
it because the module is powered from the drive control unit by default.
